Replacement Compatibility

Confirm the full A06B-6321-H311 nameplate, 180mm width, input supply, L/M/N motors, spindle motor, feedback devices, connectors, CNC software and parameters. Do not substitute A06B-6320-H311, A06B-6321-H312 or A06B-6321-H332 based on appearance.

Testing and Installation Notes

REACO CNC checks the label, housing, fans, connectors, regenerative circuit, power stages, communication, alarms and servo/spindle channels as applicable. Back up all parameters before replacement. Qualified personnel must isolate power and confirm complete DC-bus discharge before installation.
